PowerShell Remoting Requirements for Custom EXE/Script Advanced Sensor

Votes:

0

I've created a script for checking the TLS certificate assigned to an SMTP Relay server which supports SMTPS. The code is available here if that's of interest.

The documentation says that powershell remoting is required on the target system... but it's not clear what's meant by target; i.e. is that:

  • The PRTG Core Server
  • The PRTG Probe Server on which the sensor is configured
  • All PRTG Probe Servers - The Device being monitored

My guess is that it's the device being monitored; but I don't want the script to be run on that device; I want it to be run on the probe, but for its result to show under the device (i.e. as I want to show the results when a client connects to the remote service, as part of the purpose of the sensor is to show the port is available externally).

## Questions:

  • Could you confirm what servers require remoting to be enabled?
  • If the script is run on the device under which the probe's configured, is there a way to change this behaviour so I can run it from the probe whilst having the result show against the target device?

Hi there,

Yes powershell remoting is required on the target system which means the device which you want to query. However, the script will not be executed on the target system, it's executed on the server where the Probe is installed. But if you want to query the target device, your powershell code need to send a command to the remote device which allows this only if powershell remoting is enabled.
